Rank-Turbulence Delta and Interpretable Approaches to Stylometric Delta Metrics
The study introduces two new measures for authorship attribution: Rank-Turbulence Delta and Jensen–Shannon Delta. These methods generalize classical Burrows’s Delta using probabilistic distance functions derived from word frequency distributions. The results show that Rank-Turbulence Delta performs comparably to Cosine Delta, while Jensen–Shannon consistently matches or beats the traditional Burrows’s Delta, offering a more interpretable way to analyze stylistic differences.
